This read-only object indicates whether an output sub-unit supports offset stacking, in which successive print jobs or copy sets are physically shifted sideways in the bin, and whether that feature is enabled. An admin managing a shared printer used by multiple people checks this to know whether separate jobs will land in visibly distinct, offset piles for easy separation at the output tray. For example, with this set to ePon(3), two consecutive jobs sent by different users would be shifted relative to each other in the bin, making it obvious where one job ends and the next begins.
